42 bro it’s pretty simple just multiplication
Answer:
18%
Step-by-step explanation:
Non fiction books - 72
Fiction Books - 328
Total Books - 400
72 + 328 = 400
Percent of non fiction books to book fair - 18%
Simplify it until it has a denominator of 100, since that is the standard denomination for percentages.
18% or 0.18.
So in distributive property you multiply the outside number by the two inside so in this case 2(a) + 2(-2) = 3(a) + 3(-5)
Which will give you
2a+ - 4 = 3a + - 15
Or
2a-4=3a-15
Then if your solving for a your can subtract 3a from 2a giving you
- a-4=-15
Then add 4 to - 15
-a =-11
Then divide by negative 1 (this is so a isn't negative)
A=11
Hope this helps!
Answer:
A
Step-by-step explanation: Well 15:30 I would think is just 1:2 so looking for another ratio like that there's only one other answer. 3:6 15 is half of 30 and 3 is half of 6.
